I have a M37 and have the same issue in Connecticut. Here is what I learned from digging up info myself. Neither Sirius or the Dealer could figure out why the traffic flow is so limited in most Infiniti models except the Q50. I noticed many new makes, Chrysler, Ford and some others have great traffic flow. All highways and most major roads. Other makes such as Infiniti, GM, and many more have limited traffic flow even in the market area. Reason is this: Sirius has TWO traffic services depending on your vehicle make. SiriusXM traffic (this is the good one) and NavTraffic (dated and limited). All infiniti models except the new Q50 have Nav Traffic. Even the new QX80! I can't post a link so google this phrase: "SiriusXM traffic versus Nav Traffic". Find the link to Sirius Nav traffic pricing. The drop downs tell the sad story. The Sirius website does not even explain the difference and the coverage map is for Nav Traffic when it states SiriusXM Traffic. Unfortunately I think we are stuck with it..
